	* config/tc-mips.c (prev_nop_frag): New static variable.
	(prev_nop_frag_holds): New static variable.
	(prev_nop_frag_required): New static variable.
	(prev_nop_frag_since): New static variable.
	(append_insn): If we aren't reordering, and prev_nop_frag is not
	NULL, and we don't need any nops, then decrease the size of
	prev_nop_frag.  Don't insert nops because of instructions in
	noreorder sections.  Remember whether the previous instructions
	where in noreorder sections even when not reordering.
	(mips_no_prev_insn): Add preserver parameter.  Change all
	callers.  Refer prev_nop_frag variables when appropriate.
	(mips_emit_delays): Set up prev_nop_frag.
	(s_mipsset): Clear prev_nop_frag if reordering.
